Title: Oscillation switching circuit for radio receiver
Inventor: HAMANAKA HIROSHI
IPC: H04B1/26
Filed: 1985-10-31
Abstract: PURPOSE:To reduce variation in oscillation frequency with a source voltage by flowing a current to one diode during switching and also applying a reverse bias to the other diode in an off state through a coil at the same time. CONSTITUTION:A band changeover switch 21 is switched to the stage of continuity between terminals (a) and (c) for FM broadcast reception. Consequently, a current flows through a resistance 7, choke coil 4, a changeover diode 2, an FM oscillation coil 12, and a resistance 18 in order. Then, a voltage divided by resistances 6 and 7 is applied as a reverse bias to a changeover diode 14 through a choke coil 1. Then, the switch 21 is switched to the state of continuously between terminals (a) and (b) for TV broadcast reception. Consequently, the current flows through a resistance 19, a TV oscillation coil 17, a diode 14, a choke coil 1, and a resistance 6 in order. A voltage divided by resistances 18 and 19 is applied as a reverse bias to the diode 2 through the coil 12. Consequently, variation in the capacity between diode terminals becomes small and variation in oscillation frequency is reduced.

Title: Picture recording and reproducing device
Inventor: KINOSHITA MASAKATSU
IPC: G11B20/10
Filed: 1988-09-30
Abstract: PURPOSE:To perform excellent synchronous reproduction by delaying the recording operations of digital sound signals on a recording medium until digital video signals of one screen quantity are recorded on the recording medium. CONSTITUTION:An address generation circuit 35 outputs a write address for storing digital sound signals latched by a shift register 29 to a memory 31 by performing increment at every sampling clock period. The circuit 35 along outputs a value which is obtained by subtracting a prescribed numeral 'N' from the write address to the memory 31 as the readout address of the digital sound signals outputted to a shift register 32. Therefore, digital sound signals supplied to an input terminal 28 are delayed and obtained from an output terminal 34. When the delay time is correlated with the time required for recording digital video signals of one screen quantity in the sub-code data area of a tape, the time lag between a picture and sounds at the time of reproduction can be compensated. Therefore, synchronous reproduction becomes possible.

A window-structure semiconductor laser having good controllability can be realized without using an unnecessary heat-history such as Zn diffusion by growing a crystal after depositing the surfactant on the substrate in the form of a pattern.

Abstract: PURPOSE:To prevent a heat transferring operation from failing because of scale adhesion, and to prevent the heat transfer pipe in a layer from wearing by a simple way, by operating a fluidized bed furnace by mixing a fuel or a chemical agent which contains vanadium or/and sodium with a main fuel. CONSTITUTION:A main fuel being fed from a main fuel banker 6, and an auxiliary fuel such as oil coke containing vanadium and sodium, being fed from an auxiliary fuel banker 7, are thrown into a fluidized medium to burn in a fluidized bed 1, being mixed with each other while they are fed into the fluidized medium.
